Nano Bubble Technology Reduces 95% Water in Denim Washing

Denim is considered the most interested field in the glob for creating new fashion. Researchers are developing new technology considering sustainability that leads to invent processes that can go through environmental friendly way.

Nano Bubble Technology is the new one which is widely known as e-flow system was invented and patented by Jeanologia, a Spanish company in the year 2012 and now it is coming into force in industrial use for denim washing. In fact it is the sustainable finishing process for textile that transfers chemicals on to garments made of any fabric. Water, which is the main career of any finishing process and finally discharges into environment as waste but in e-flow system air from the atmosphere is transformed into the nano bubbles where water and correct amount of chemical products naturally distribute themselves forming the nano bubble skin. Therefore, they can be used as the carriers of the chemicals and transmit them homogeneously onto the garment.

This technology can contribute to a considerable number of finishing effects with the best level of quality, a maximum less amount of water and there is zero discharge of the process.

Methodology:

Air from the atmosphere is taken into an electro-flow reactor and subjected to an electro-mechanical shock that creates nano bubbles and a flow of wet air.

Then the nano bubbles are transported into a rotating tumbler containing the denim samples and when it comes into contact with them produces a soft and natural hand feel. The samples are then dried even in the same tumble machine it is possible to dry up. Since denims are indigo dyed where unfix dyes are available on the surface of the fabric therefore cross staining may happen with this technology which can be eliminated through using a little bit anti cross staining agent or can treat with dry ozonator.

The e-flow process breaks up the indigo molecules from the surface of the denim and then the process produces a pre-shrinkage of the fabric, that will contribute to avoid high shrinkage during home laundry. It also gives a softer hand feel and so the garments are comfortable to wear and with an improvement in color fastness to rubbing properties.

Five benefits of the process:

• It reduces 95% water and 40% energy consumption.
• Elimination of waste water and treated chemical to the environment.
• Superb hand feel can be achieved
• High quality garments are treated which are being affected by conventional wash process.
• The brightness and luster are increased
